Predictika · Harbour tug orders

An AI sales agent's harbour tug order, checked before it goes out

An AI sales agent prepares a harbour tug order: the tug model, diesel or electric propulsion, fire-fighting, crane and aft winch options, the number of tugs, the crew, the bollard pull the operation needs, the draught the home port allows, the delivery time and the bollard pull the order states. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of how these choices fit together, and returns a verdict, every reason and the figures it computed.

Scope: One harbour tug order: model, propulsion, options, number of tugs, crew, bollard pull, port draught, delivery time and the stated bollard pull. See everything this validator covers

This validator models six tug models and their options, not just the scenarios shown below.

  • Models — ASD Tug 2111, 2312, 2811, 2813 and 3212 and RSD Tug 2513, each with its own bollard pull, crew capacity and draught.
  • Propulsion and options — diesel or electric, where the electric version is offered, and fire-fighting, crane and aft winch with the combinations each model takes.
  • Operation fit — the bollard pull the operation needs, the crew on board, the draught against the home port, and ice class, which none of these models is.
  • Order terms — number of tugs, fleet orders that need a commercial review, delivery time, and the stated bollard pull compared with the tug on the order.

Any tug order that touches these rules is in scope — not only the scenarios pictured here. Not covered: other Damen vessel types and prices. The model names, bollard pull, crew, draught and options come from public Damen tug pages; Damen does not publish its option exclusions or approval thresholds, so those are modeled from comparable tug builders and are not published by Damen. No prices are modeled.

The AI sales agentBuilds the tug order from the conversation with the customer and says it is ready to send.
Predictika validatorChecks every rule at once and returns the verdict, each finding, and the computed figures.

Where rules-based CPQ gets it wrong
Click to expand
    
Our assessment of what a typical rules-based CPQ (product rules, price rules and validation rules, as in Salesforce CPQ) does with the same cases. It is a judgment about effort and reliability, not a claim that nothing can be built.

    
What the validator caughtTypical rules-based CPQPredictika
Options that depend on the modelOnly with workarounds
A crane is not offered on one model, a crane and an aft winch exclude each other on the two smallest decks, and each exclusion differs by model.		Model and options are fields of one order and are checked against each other on every call.
Propulsion that changes the figuresOnly with care
Electric versions exist for two models only, carry a lower bollard pull, and do not combine with fire-fighting, so one choice changes several limits.		Propulsion, model and the computed bollard pull are checked together.
Operation requirements against the tugOnly with care
The bollard pull, crew and draught the operation needs must each be compared with a value that depends on the model and propulsion.		Required and delivered figures are compared on every call, and the reasons are listed together.
Blocks and approvals at onceOnly with workarounds
A fleet order and a short delivery time need a person while a wrong option stops the order, and both should be seen together.		Blocks and approvals are reported together, so one problem never hides another.
A stated figure that must match the tugOnly with workarounds
The bollard pull on the order depends on model and propulsion, so a separate rule must recompute it and compare it with the stated figure.		The stated bollard pull is a field of the order and is compared with the computed one on every call.

  

  

    
What this validator catches: findings from its test cases
Click to expand
    
Every rule is checked on every call, in any order the choices arrive; one problem never hides another. Blocking findings stop the order; approval findings need a person to sign off; everything else is computed.

    
1An electric version is listed for the ASD Tug 2111 and the RSD Tug 2513 only.
2Ice-class tugs are separate Damen designs (for example the ASD Tug 3413 ICE); none of the models on this order is ice class.
3The ASD Tug 3212 is offered with an aft winch, not a crane; choose another model for a crane.
4The working deck of the ASD Tug 2111 and 2312 takes a crane or an aft winch, not both.
5The fire-fighting package is ordered with the diesel tugs; it is not combined with an electric version here.
6The operation needs 85 t of bollard pull; the tug on the order delivers 80 t.
7The order plans 11 crew; the tug accommodates up to 10.
8The tug draws up to 590 cm; the home port allows 550 cm.
9The quote states 80 t of bollard pull, but the tug on the order delivers 60 t.
10An order of 4 tugs or more is a fleet deal and needs a commercial review.
11The order has 0 tugs.
12The RSD Tug 2513 is not listed as ready from stock; delivery in 17 months needs the yard to confirm a build slot.
13Options fitted to a stock tug with delivery in 3 months need the yard to confirm the conversion time.
14The order asks for delivery in 0 months.

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. An AI sales agent prepares a harbour tug order: the tug model, diesel or electric propulsion, fire-fighting, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of how these choices fit together, and returns a verdict, every reason and the figures it computed.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please quote 4 electric ASD Tug 2312 tugs with fire-fighting, a crane and an aft winch, delivery in 14 months. The order states 70 tons of bollard pull. The rest of the request is on screen.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with seven findings and one approval, all in one answer. An electric version is listed for the ASD Tug 2111 and the RSD Tug 2513 only. The working deck of the ASD Tug 2111 and 2312 takes a crane or an aft winch, not both. The fire-fighting package is ordered with the diesel tugs; it is not combined with an electric version here. The other four are on screen.
    6. 
      
  6. The validator returned seven blocking findings and one approval in one answer. A check that reads one field at a time would pass most of this; it shows only when the choices in the order are checked against each other.
    7. 
      
  7. What this shows: for operation requirements against the tug, a rules-based CPQ is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the model to ASD Tug 2813, the propulsion to diesel, the aft winch to no and the stated bollard pull to 80 tons.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. Still blocked, with one finding and one approval, all in one answer. The tug draws up to 615 cm; the home port allows 520 cm.
    12. 
      
  12. Six findings cleared. Still blocking: draught deeper than the berth. One approval also remains for a person: fleet order to review.
    13. 
      
  13. The agent resubmits once more.
    14. 
      
  14. The revised request. It changes the home port draught to 6.5.
    15. 
      
  15. It calls the validator once more.
    16. 
      
  16. Not blocked, but held for a person.
    17. 
      
  17. The one blocking finding is cleared; one approval remains for a person: fleet order to review.
    18. 
      
  18. The agent resubmits again.
    19. 
      
  19. The next revised request. It changes the tugs to 3.
    20. 
      
  20. It calls the validator yet again.
    21. 
      
  21. This time the validator clears it.
    22. 
      
  22. The earlier finding is cleared.
    23. 
      
  23. Eight problems caught in one call, fixed in three passes, and a clean order. That is the value of Predictika's validator: catching mistakes before they reach the customer. Now you can try the other scenarios yourself.
    24.
